Architecting Innovative Registers for the Future

This technical report presents a systemic view for the operation of a register, focusing on the architectural principles necessary for effective register systems. The authors discuss the challenges faced by registers in deciding whether to custom-build or procure systems, emphasizing the importance of a defined Target Operating Model (TOM) and guiding principles. The report outlines the deficiencies of internal custom builds and the risks associated with vendor lock-in when procuring systems. It further details how architectural principles can improve system quality, consistency, and efficiency, while also facilitating maintenance and evolution. The authors propose a Capability Maturity Model (CMM) for registers to provide a framework for comparison and improvement. Additionally, the report highlights current trends in the register domain, including the shift towards cloud-based platforms, which offer scalability, flexibility, and enhanced security measures. Overall, the document aims to establish a foundation for future register operations through clear architectural guidelines.
